* tests: Add replay-back-edge testMartin Braun2021-12-091-0/+44
| | | | | | | | | This tests the following graph: DDC -> Replay -> DDC, where the initial and final blocks are the same (i.e., a loop). This could be useful for generating and capturing data with the same replay block while testing a block. Note that this test will fail if the edge consistency checks are buggy.
* rfnoc: Clarify usage of MTU vs. max payload size, remove DEFAULT_SPPMartin Braun2021-12-022-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These two values where being mixed up in the code. To summarize: - The MTU is the max CHDR packet size, including header & timestamp. - The max payload is the total number of bytes regular payload plus metadata that can be fit into into a CHDR packet. It is strictly smaller than the MTU. For example, for 64-bit CHDR widths, if a timestamp is desired, the max payload is 16 bytes smaller than the MTU. The other issue was that we were using a magic constant (DEFAULT_SPP) which was causing conflicts with MTUs and max payloads. This constant was harmful in multiple ways: - The explanatory comment was incorrect (it stated it would cap packets to 1500 bytes, which it didn't) - It imposed random, hardcoded values that interfered with an 'spp discovery', i.e., the ability to derive a good spp value from MTUs - The current value capped packet sizes to 8000 bytes CHDR packets, even when we wanted to use bigger ones This patch changes the following: - noc_block_base now has improved docs for MTU, and additional APIs (get_max_payload_size(), get_chdr_hdr_len()) which return the current payload size given MTU and CHDR width, and the CHDR header length. - The internally used graph nodes for TX and RX streamers also get equipped with the same new two API calls. - The radio, siggen, and replay block all where doing different calculations for their spp/ipp values. Now, they all use the max payload value to calculate spp/ipp. Unit tests where adapted accordingly. Usage of DEFAULT_SPP was removed. - The replay block used a hardcoded 16 bytes for header lengths, which was replaced by get_chdr_hdr_len() - The TX and RX streamers where discarding the MTU value and using the max payload size as the MTU, which then propagated throughout the graph. Now, both values are stored and can be used where appropriate.

* rfnoc: ddc: Improve unit tests and documentationMartin Braun2021-08-301-5/+19
| | | | | | | The previous commit fixed a bug in the DUC, where get_frequency_range() reported incorrect values. The DDC did not have this bug, but we port the updates to the unit tests and the documentation from the DUC to the DDC for consistency's sake.
* rfnoc: duc: Fix frequency range for DUC blockMartin Braun2021-08-301-7/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuning range of the DUC depends on the output sample rate (which is larger), but it was using the input sample rate. This was causing a bug where for Tx, the DSP tuning range was limited when using multi_usrp API, and thus would not allow to DSP-tune beyond the current sampling rate. In this patch, we also re-use the existing calculation of the sampling rate, and harmonize that code between duc_block_control and ddc_block_control. Consider the following Python REPL code: >>> import uhd >>> U = uhd.usrp.MultiUSRP('type=x300') >>> U.set_rx_rate(10e6) >>> U.set_tx_rate(10e6) >>> # Creating a streaming is required, or the input rate will not be >>> # set: >>> S = U.get_tx_stream(uhd.usrp.StreamArgs("fc32", "sc16")) >>> treq = uhd.types.TuneRequest(1e9) >>> treq.rf_freq = 1e9 >>> treq.dsp_freq = 50e6 >>> treq.dsp_freq_policy = uhd.types.TuneRequestPolicy.manual >>> treq.rf_freq_policy = uhd.types.TuneRequestPolicy.manual >>> tres = U.set_rx_freq(treq, 0) >>> print(str(tres)) Tune Result: Target RF Freq: 1000.000000 (MHz) Actual RF Freq: 1000.000000 (MHz) Target DSP Freq: 50.000000 (MHz) Actual DSP Freq: 5.000000 (MHz) >>> # Note the last two lines: The *target* DSP freq was already clipped >>> # to 5 MHz. These lines show 50.0 MHz when this patch is applied. This bugfix is accompanied some related changes: - The unit test is amended to verify the behaviour - The API documentation is amended with details on its behaviour
* uhd: Fix usage of std::abs with template parametersMartin Braun2021-07-231-3/+3
| | | | | | | | | `std::abs` is only a templated function, when dealing with complex numbers. For real values, it is an overload. There is no documented standard way to use `std::abs<double>()` for real-valued arguments. We therefore remove all usages of `std::abs<>()` and replace them with `std::abs()` where they were taking a real-valued argument.
* zbx: Fix clang compiler warningsMartin Braun2021-06-221-2/+2

| | | | | | M_PI may not exist if _USE_MATH_DEFINES isn't defined before the first include of math.h or cmath on Windows. This changes avoids the issue all together by defining our own PI.
